How to call graphql resolver in go












0














I have a graph endpoint(145.75.86.11:7545/graphql) I need to call graphql resolver (resolverExample) and send a string(“HELLO WORLD”) how can I do that/?



I have tried this, but it does not work



url := "145.75.86.11:7545/graphql"

var jsonStr = byte(`{
resolverExample(theme:"HELLO WORLD")
}`)
req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
req.Header.Set("X-Custom-Header", "myvalue")
req.Header.Set("Content-Type", "application/json")

client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
panic(err)
}
defer resp.Body.Close()

fmt.Println("response Status:", resp.Status)
fmt.Println("response Headers:", resp.Header)
body, _ := ioutil.ReadAll(resp.Body)
fmt.Println("response Body:", string(body))

          Try the following code, assuming the service runs on HTTP, not on HTTPS:



          url := "http://145.75.86.11:7545/graphql"
          query := `{
          resolverExample(theme:"HELLO WORLD")
          }`
          json := `{"query":` + strconv.QuoteToASCII(query) + `}`
          req, err := http.NewRequest("POST", url, strings.NewReader(json))
          if err != nil {
          req.Header.Set("Content-Type", "application/json")
          client := &http.Client{}
          resp, err := client.Do(req)
